Tata Elxsi today unveiled tis 3GPP release 8 compliant LTE UE (User Equipment) protocol stack with an aim to accelerate the time-to-market for LTE terminal devices.

The company says that the solution provides complete software for Layer 2 and Layer 3, including MAC, RLC, PDCP, RRC and NAS and also features optional LTE specific components such as RoHC v1/v2, Snow-3G, AES and Layer 1 algorithms.

Furthermore the software architecture has been designed in such a way that it ensures minimized footprint and high performance. The architecture is split into control plane and data plane to handle critical and non-time critical operations, meeting the high throughput demands of LTE UE, claims Tata Elxsi.

“We have leveraged our deep expertise in the development, integration, interop and compliance testing for CDMA, WiMAX and 3G based CPE and handset solutions, to deliver an industry-leading software solution for LTE terminal devices”, said Mr. Nitin Pai, Vice President, Marketing, Tata Elxsi.

The solution has been modularly architected for SoC implementation, and is agnostic to the underlying Operating System and hardware. The LTE UE solution also features a multi-mode controller with intelligence for inter/intra Radio Access Technology (RAT) handover to enable backward compatibility to 3G. The solution has been integrated on an embedded platform and is ready for interop-testing with eNodeB

solutions, ensuring optimum implementation and maturity.

The solution features comprehensive debug trace and statistical logging capabilities, and the descriptor-based MAC-PHY Interface enables easy adaptation of Tata Elxsi L2/L3 solution to third party L1 implementations, concludes the company.
